[0018] In order to be able to more clearly understand the technical means of the present utility model and implement it in accordance with the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model.

[0019] This specific embodiment details the assembly and detection mechanism described in the present application, as shown in Figure 1 and Figure 2As shown in the figure, the assembly detection mechanism includes: a lifting mechanism 1, an assembly mechanism, a fixing mechanism 2, an adsorption mechanism, a connecting block 3, a connecting seat 4, and a pressure sensor 5. The connecting seat 4 is fixed to the moving end of the lifting mechanism 1. The connecting block 3 is fixed to the top of the adsorption mechanism. The connecting block 3 is slidably connected to the side of the connecting seat 4 in the vertical direction. A limiting block 10 is provided on the connecting seat 4. A limiting groove is formed on the side wall of the connecting block 3. The first end of the limiting block 10 can extend into the limiting groove, and the first end of the limiting block 10 can abut against either the upper wall or the lower wall of the limiting groove. The assembly mechanism and the fixing mechanism 2 are fixed to the connecting seat 4 above the adsorption mechanism. The pressure sensor 5 is fixed to the second end of the limiting block 10. The detection end of the pressure sensor 5 is connected to the top of the adsorption mechanism through a connecting rod. The assembly mechanism is provided with an assembly end that can push the workpiece in the vertical direction. The fixing mechanism 2 is provided with a pushing end that can push the connecting block 3 in the vertical direction. The assembly mechanism, the fixing mechanism 2, the adsorption mechanism, the connecting block 3, the connecting seat 4, and the pressure sensor 5 can move back and forth in the vertical direction under the drive of the lifting mechanism 1. The bottom end of the adsorption mechanism can adsorb the workpiece. The workpiece adsorbed on the adsorption mechanism can be pushed away from the adsorption mechanism by the assembly mechanism and then fixed at the installation position. The connecting block 3 can be pushed downward by the fixing mechanism 2 until the first end of the limiting block 10 abuts against the upper wall of the limiting groove. The bottom end of the adsorption mechanism can squeeze the workpiece under the drive of the lifting mechanism 1. During use, first place the product on which the workpiece needs to be installed below the adsorption mechanism, and the installation position on the product is directly opposite to the workpiece adsorbed on the adsorption mechanism. Then the fixing mechanism 2 pushes the connecting block 3 downward until the first end of the limiting block 10 abuts against the upper wall of the limiting groove. At this time, the connecting block 3 and the adsorption mechanism are in a fixed state. Then the adsorption mechanism with the adsorbed workpiece moves downward under the drive of the lifting mechanism 1 until the workpiece approaches the installation position. Then the assembly end of the assembly mechanism extends out to push the workpiece away from the adsorption mechanism, and then continues to push the workpiece until the workpiece is fixed at the installation position to complete the assembly of the workpiece. Then the assembly mechanism and the fixing mechanism 2 return to their original positions. At this time, due to the loss of the push of the fixing mechanism 2, the connecting block 3 and the adsorption mechanism are in a sliding state, providing conditions for the detection of the pressure sensor 5. The adsorption mechanism descends a predetermined height under the drive of the lifting mechanism 1. When the workpiece is correctly fixed at the installation position, the bottom end of the adsorption mechanism can squeeze the workpiece. At this time, the pressure sensor 5 can detect the pressure value when squeezing the workpiece. When the pressure value meets the standard value, it is judged that the workpiece is fixed accurately. When the workpiece is not accurately fixed at the installation position, the pressure sensor 5 cannot detect the pressure value, or the detected pressure value does not conform to the standard value, then it is judged that the workpiece is not fixed accurately. Since the entire assembly and detection process is completed automatically, the automation degree is high. It has the advantage of high automation degree.
